Oil and Natural Gas Properties [Abstract]
OIL AND NATURAL GAS PROPERTIES	OIL AND NATURAL GAS PROPERTIES Dispositions In October 2019, Barnwell entered into a purchase and sale agreement with an independent third party and sold its interests in properties located in the Progress area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $594,000 in order to, among other things, reflect an economic effective date of October 1, 2019. The final determination of the customary adjustments to the purchase price has not yet been made however it is not expected to result in a material adjustment. The proceeds were credited to the full cost pool, with no gain or loss recognized, as the sale did not result in a significant alteration of the relationship between capitalized costs and proved reserves. There were no oil and natural gas property dispositions during the three months ended December 31, 2018. The $633,000 of proceeds from sale of oil and gas properties included in the Condensed Consolidated Statement of Cash Flows for the three months ended December 31, 2018 represents the refund of income taxes previously withheld from what otherwise would have been proceeds on the previous years' oil and natural gas property sales. Acquisitions There were no significant amounts paid for oil and natural gas property acquisitions during the three months ended December 31, 2019. In the quarter ended December 31, 2018, Barnwell acquired additional working interests in oil and natural gas properties located in the Wood River and Twining areas of Alberta, Canada for cash consideration of $355,000.

The customary purchase price adjustments were finalized in the quarter ended June 30, 2019 and resulted in an immaterial adjustment. Impairment of Oil and Natural Gas Properties Under the full cost method of accounting, the Company performs quarterly oil and natural gas ceiling test calculations. There was no ceiling test impairment during the three months ended December 31, 2019. There was a ceiling test impairment of $2,170,000 during the three months ended December 31, 2018. Changes in the 12-month rolling average first-day-of-the-month prices for oil, natural gas and natural gas liquids prices, the value of reserve additions as compared to the amount of capital expenditures to obtain them, and changes in production rates and estimated levels of reserves, future development costs and the market value of unproved properties, impact the determination of the maximum carrying value of oil and natural gas properties. In addition, the ceiling test is also impacted by any changes in management's quarterly evaluation of the Company's ability to fund the approximately $12,000,000 of future capital expenditures necessary over the next five years to develop the proved undeveloped reserves that are largely in the Twining areas of Alberta, Canada, the value of which is included in the calculation of the ceiling limitation. If facts, circumstances, estimates and assumptions underlying management's assessment of the Company's ability to fund such capital expenditures change such that it is no longer reasonably certain that all of the approximately $12,000,000 of capital expenditures necessary to develop the proved undeveloped reserves can be made, it is likely that we will incur a further ceiling test impairment at that time.

Dispositions

In October 2019, Barnwell entered into a purchase and sale agreement with an independent third party and sold its interests in properties located in the Progress area of Alberta, Canada. The sales price per the agreement was adjusted for customary purchase price adjustments to $594,000 in order to, among other things, reflect an economic effective date of October 1, 2019. The final determination of the customary adjustments to the purchase price has not yet been made however it is not expected to result in a material adjustment. The proceeds were credited to the full cost pool, with no gain or loss recognized, as the sale did not result in a significant alteration of the relationship between capitalized costs and proved reserves.

There were no oil and natural gas property dispositions during the three months ended December 31, 2018. The $633,000 of proceeds from sale of oil and gas properties included in the Condensed Consolidated Statement of Cash Flows for the three months ended December 31, 2018 represents the refund of income taxes previously withheld from what otherwise would have been proceeds on the previous years' oil and natural gas property sales.

Impairment of Oil and Natural Gas Properties

Under the full cost method of accounting, the Company performs quarterly oil and natural gas ceiling test calculations. There was no ceiling test impairment during the three months ended December 31, 2019. There was a ceiling test impairment of $2,170,000 during the three months ended December 31, 2018.

Changes in the 12-month rolling average first-day-of-the-month prices for oil, natural gas and natural gas liquids prices, the value of reserve additions as compared to the amount of capital expenditures to obtain them, and changes in production rates and estimated levels of reserves, future development costs and the market value of unproved properties, impact the determination of the maximum carrying value of oil and natural gas properties. In addition, the ceiling test is also impacted by any changes in management's quarterly evaluation of the Company's ability to fund the approximately $12,000,000 of future capital expenditures necessary over the next five years to develop the proved undeveloped reserves that are largely in the Twining areas of Alberta, Canada, the value of which is included in the calculation of the ceiling limitation.
